Title: Odd warning light behaviour (Code 0430)
Post by: Albatross on 22 June 2008, 14:46:34
I have the familiar 3.2/2.6 known 0430 issue where the pre-cat on the near side is being declared as "a bit tired".

I have a solution which is being fitted next week at long-life, but my warning lights behaved very strangely this week.

My EML light (The one with the side veiw of an engine) is on pretty consistently nowadays and I've got used to it. It is always related to code 0430 so there's no huge concern there, but earlier this week that light went out and the service light (The one with the side veiw of the car and a spanner) came on. It wasn't flashing or anything and the car behaved as normal. I rang my friendly local independent garage, who is aware of my EML light and emmissions issue, and he said not to worry and that it was only due to the same issue that had been outstanding for so long that the car is now trying to get more serious about telling me to get the system sorted.

Fine I thought I'll just wait until next weekend, change the exhaust, move the secondary lambda sensors further back in the system and get the lights cleared / reset.

What is strange though is that driving along half an hour ago the lights have just reverted so that the spanner light has gone out and the EML (engine picture) light has come back on.

It's Sunday and I can't check the codes myself on this car (facelift 3.2) with a paperclip, so does anyone have any ideas?

All I can add is that my EML light was on for the same, then one day I started it and it vanished...

It might be that it was struggling with fuel trim for a short period but has now recovered.

I take it the brake/accelerator trick does not work on yours then?

Depress brake and throttle to the floor simultaneously and turn the key to position II (ie, electronics on but not starter), code will flash out on EML lamp - not emissions lamp.

NB. the emissions lamp is the icon of the engine the eml lamp is the icon of the car with the spanner though it, i've only ever seen emissions codes illuminate the emissions lamp.

Thanks for that.

OK done that. I get in quick succession ten four three ten, so I'm guessing that 0430, which is what I was told at the garage initially.

Then after a few seconds I got 4 flashes which were a little further apart.

This was all on the EML (car/spanner icon) light.

Once I then started the car I got all lights off except the emmissions light (engine icon).

Is everything as I suspected? Was this just "struggling with the fuel trim" and what does that mean?
